Tekin Pro4 HD Brushless Motor - First Look!

Here's a look at the new Tekin Pro4 HD 550 sized motor. This is intended for my new Tekno SCT410 and will have tons of torque and a bit of speed, as I chose the 4300kv version. The new HD is available a 5 different kv sizes including 4300, 3500, 3000, 3500 and 1850, but does require different voltages to make each motor optimal.
Here's a link to where I got it and some info from Tekin:
Tekin's Pro4 HD Motor raises the bar in offroad power. The Pro4 HD's longer 550 can and 4 pole design provide performance gains across the board and off the charts when compared to standard 1:10th scale motors. The Pro4 HD has the torque and power to level the competition. Designed for use with 2S-4S power systems, 1:10 4WD Short Course has never had this kind of power! Combine the Pro4 HD with a Tekin RX8 ESC in your 4WD Short Course and hold on!
